Question

Using Figure 4, complete these functions.

Answer 1

Answer:

• D. 21/29

Step-by-step explanation:

Formulas used:

• sin θ = sin (180 - θ)
• sin θ = opposite/hypotenuse

Opposite:

• y- coordinate of given point = 21

Hypotenuse:

• √x²+y² = √20²+21²= √841 = 29

Then

• sin θ = 21/29

Correct choice is D
